I have bought a thinkpad t440s

i7
it is bios locked, i CANNOT buy new motherboard
which chip do i need to dump? i can buy clip to do this, i have a t48, but have no idea where this mystical chip is or where to find it

after it is dumped, can i use the util from the first post or do one of u have to do it?

this computer is worthless to me without bios unlock, i would be better throwing it away if this does not work

Right above the RAM dimm.

Hi!
I have problem with locked T540p
With original (locked) 4MB file works fine, with the patched nothing just blank screen and power led on.
Tried to read again, repatch, rewrite, no luck.
Patcher completes with error "Looking for volumes to patch... [1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h): Not found... Skipping."

What is that?

Problem solved with 4MB file from post #11 of another thread.
Seems like AutoPatcher is unable to correctly patch the 4MB file and produces the above error, this user manually patched it and works like a charm.
Keep in mind that motherboard needs the LAN & USB daughterboard to be connected in order to power up, otherwise doesn't boot!
Thank you all!

Just preparing for when I am able to get access to a programmer. Might take a couple of weeks to get it , my country is not so easy to get deliveries quickly, figured I'd get this part of the process done if possible.

Hello, trying to remove forgotten supervisor pw from my bios, need to do an OS install, pc boots into windows fine but I don't have the a tools to get dump file from the chip physically. Tried to extract a bin from the .exe (which I also included) I last updated the bios with, but I am not that computer literate and I am just confused now. I did find a bin for my 20EQ motherboard but I don't know if it needs to be specifically obtained from my pc.

PC DETAILS:

LENOVO P50 INTEL Ci7 6820HQ

SERIAL - PC0TNEGH

MBOARD - 20EQS4QM00 SDK0J40697 WIN

CURRENT BIOS VERSION: N1EETA2W (1.75)

Suppose when you have the bios patch, how do you write it to the bios chip ?

Can I get a patched bios

[grizzlyd]

I might sound like a complete idiot here but I have generated a patched .bin file using the autopatcher for my L480. Now how do I flash my current bios with this file??

[DoCNC]

Unfortunatly every time I fail to save the PC, after all this I try to boot the PC and it is still locked.

It looks like you may have a HDD pwd installed?
please remember: the script from Knucklegrumble
ONLY remove the BIOS Supervisor password… Nothing else…

Hello.

I am trying to salvage Bios locked Lenovo T480 Type 20L5.
I tried couple of times to follow the guide of reading BIOS with NeoProgrammer, autopatching it with Python script, writing onto chip, following the GUIDE and then rewriting original image with erase and verify on.
Unfortunatly every time I fail to save the PC, after all this I try to boot the PC and it is still locked.
Anyone can help me with it, or guide me where am I making mistake?
I am including my original BIOS image with "patched one"

Corrupted bios or lost resistors near the chip.
Try original bios or put another one.
Too many problems with these cheap programmers.
If white screen probably bios problem
Don't use clamp
